IMPROVEMENT IN SELF-ACTING SPINNING-MULES.

Improvements in Self-Acting Mules. My invention consists of certain improvements in selfacting mules,

fully described hereafter, whereby I am enabled to dispense with the usual complicated appliances for regulatin g the dles.

In the accompanying drawing,

winding of the yarn upon the spin- Figure 1 is a side elevation of sufficient of a self-actin g mule to illustrate my improvement view of the same; and Fig. 3

all of such well-known parts-such, for instance, as the vertical cam-shaft and transmitting devices, which need no t necessarily be shown in illustrating my improvementshave,

in order to enable the latter to be represented more prominently, been omitted from the drawing.

The ordinary parts represented are the fixed frame or head-stock A, driving-shaft D, with the carriage B, and the its loose pulley E, fast -pulley E pulley E for operating the slubbin g devices, and pulley E for operating the twist- 7 ing mechanism; besides which a cog-wheel and clutch, hereafter referred to, and the belt-shifter G, are also shown.

is controlled and actuated b The belt-shifter, however, is not operated in the usual manner, but

y a cam, a, on a horizontal cam-shaft, F, which receives its motion from the ordinary vertical cam-shaft, as will be more fully described hereafter.

Ordinarily the carriage is from the head-stock by simpl ing their motion from the fast driving-shaft; but in order to ing in of the carriage and th yarn upon the spindles b it is a complicated arrangement of rant, chains, springs, catches,

moved outward e devices, derivpulley E on the eflect thedrawe winding of the usual to employ toothed quadand other applideriving their movement from the loose pulley E, which, when the motion 0 f the carriage is reversed, is made fast by certain automaticallyoperated devices, which can be thrown off when it is necessary to stop the mule at the end of the drawing in and winding operations.

By means of my invention, which I will now proceed to describe, I am enabled not only to dispense with all of the above-mentioned complicatedappliances, but to draw in the carriage by the same devices which are used to move it outward, and also to regulate the winding operation by means of a few appliances of the most simple character, controlled by the pulley E the latter also actuating the said devices by which the movements of the carriage are controlled. The front or stripping fallcrrod H on the carriage is provided with an arm or crank, d, jointed at its outer end to a vertical rod, I, guided by and arranged to slide through a bracket, 6, of the carriage, and. furnished at its lower end with two anti-friction rollers, f and f, the former of which bears against the upper, and the latter against the lower edge of a lever, J, Fig. 1, which is of as great or greater length than the head-stock, and has its fulcrum at a point, g, upon or ad-- iacent to the outer end of the latter. The said lever J is connected by a chain or rope, it, passing over a pulley, t, on the head-stock, to the outer end of a horizontal friction-lever, K, having its fulcrum at a point, j, on the head-stock,

the connection being made by means of a regulating-screw, Ir, which is operated so as to shorten the chain and form the cop. The friction-lever K is acted on by a strong spiral spring, L, or its equivalent, which tends to draw the said lever in the direction of the arrow 1, Fig. 2, and thus forceit against a frictionclutch, m, by which the cog-wheel n and the ordinary twisting devices deriving their.

motion therefrom are thrown into and out of gear with the pulley E on the driving-shaft. It should be understood, however, that the clutch is not operated by the friction-lever K, but merely held up to its work by the same, the said clutch deriving its motion from a clutch-lever, p, constantly acted on by a spring, which tends to throw it outward, and forced inward at the proper intervals by a cam or its equivalent. Whatever movement, however, is given to the clutch must be imparted tothe friction-lever bearing against the same, which movement is transmitted through the chain h to the lever J and thence to the faller-rod H,

thus regulating the winding, as hereafter described.

The operation of the mule, or of that portion of it to which my invention relates, is as follows: The carriage is moved outward from the head-stock, as usual,- by devices connected with and receiving their motion from the fast pulley E the slubbing receiving during this motion the necessary slight'twist; and when the carriage has been moved about half way out the paying out of the slubbing ceases and the drawing commences; the driving-belt is then automatically shifted by the fork G partially onto the pulley E which increases the twist and the speed of the carriage. The belt is next, after the carriage has reached the limit of its outward movement, shifted to the pulley E which, through the cog-wheel n and clutch m, now held up against it by the friction-lever K, operates the twisting mechanism and finishes the thread. As soon as the twisting has been accomplished the whole movement is reversed, as usual, by means of the vertical cam-shaft, which also, through the medium of the clutchlever 12 and cam 4 on the horizontal camshaft F, moves the clutch m and friction-lever Kin the direction of the arrow 2, and thus throws off the twisting mechanism, and at the same time shifts the driving-belt to a position partly on the fixed driving-pulley E and partly on the loose pulley E. The shifting of the belt to this position, instead of entirely onto the loose pulley, enables the fast pulley E to draw in the carriage by the same devices which are used for moving it outward, the direction of the motion of these devices being reversed, when the belt is shifted, by means of the vertical'cam-shaft. By means of the fast pulley and such simple devices as an endless rope and grooved pulleys on the head-stock and car'- riage I can also rotate the spindles so as to wind up the yarn as the carriage is drawn inward. The back movement of the clutch m and friction-lever K, which occurs before the shiftingof the belt, releases and lowers the lever J to the position shown in Fig. 1, so that as the carriage is drawn in the said lever J, which serves as a guide for and determines the movement of the vertical rod I, connected with the faller-rod H, will cause the said rod I to be gradually lowered as it moves over the same, thus gradually raising the arms so of the fallerrod, and causing the yarn to be properly wound upon the spindles and the cop to be properly built. When the lever K is thrown outward by the clutch it will be acted on in one direction by the spring attached to the clutch-lever, and in the opposite direction by its own spring L, and being thus held by and between two springs it will necessarily, when the machine is in operation, be caused to constantly vibrate to a slight extent, which vibration will be imparted to the lever J and thence to the fallen rod, causing the latter to rise and fall to a limited extent as it lays the thread upon the bobbin. By curving or waving the lever J, so as to cause the rod I torise and fall several times in passing over the same, I can cross the yarn as it is wound upon the spindles several times in each stretch.

Although I have referred to other devices than those connected directly with the lever J, I do not here make any claim to the same, as they form the subject of a separate application for Letters Patent.

Claim.

The combination, substantially as described, of the friction-lever K, chain or other connec tion h, building-lever J, and the devices herein described, or their equivalents, for controlling the movements of the faller-rod H from the said building-lever.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
